    I am having difficulty working with the pie chart and getting the actual pie slices to render effectively.

    Can you change the scale of a pie chart?  The problem that I am having is when I have a single value that encompasses 90% of the chart, the other pie slices and their labels are overlapping.

    I've already tried setting Intelligent labels, setting margins on the textblocks, etc.  The labels are multi-line too.  I've set the maxlength to 50.

    If you create a pie chart with the following values, you will see what I mean:

    chartSeries.AddItem(30670.80,

    "Infrastructure \n30,670");

     

    chartSeries.AddItem(776.30,

    "Energy \n$776");

     

    chartSeries.AddItem(295.30,

    "Education and Training \n$295");

     

    chartSeries.AddItem(378021.30,

    "Protecting the Vulnerable \n$378,021");

     

    chartSeries.AddItem(50.00,

    "Other \n$50");

    I am at a loss on what else to change in order to get the labels to stop overlapping each other or get the smaller percentage pie slices to show better or bigger.

    Any assistance would be greatly appricated.

    Thanks,
    Dawn

    Hi Dawn Strianese,

    Unfortunately there is not much you can do. The usual advice in your case is this:

    -Try to increase the total size of the chart (its width and height)
    -Try to lower the fontsize of the labels
    -Try to hide those labels altogether
    -Try to only display the percent i.e. "40%"

    Hope this helps.

    Have you tried the "ShowLabelConnectors" property? This could also help alleviate the issue.
